Application filed Mai-011.2, 1925. Serial No. 12,478.

This invention relatesv to a shingle ofthe variety called self-spacing and to the rocess of cutting such a shingle from a sieet of roofing material.' The invention is adapted to the sortot' shingles commonly known in the trade as manufactured shingles in which a base otfelted or fibrous material is satu rated with waterproofing material such as asphalt and is then coated with a coating of 1 plastic .material which subsequently has a layer of mineral wear resisting material such as crushed stone, slate or the like, applied thereto. By'tliis invention the shingles can be cut from a sheet of roofing material with- .15 out any waste and atthe same time the shingles will be such that they can be "very easily and readily installed with the proper spaces between shingles in horizontal rows and with the proper amount of overlap. At the same time,the danger of water passing or being blown upwardly in the spaces between the shingles and getting inside the buildings is decreased.

.. In carrying out this invention a sheet of roofing material is slit or cut in such a manner that shingles are produced having one or more projections and corresponding recesse along one edge, which projections serve to cause the shingles to be spaced in horizontal rows and also serve to form the upper ends of the spaces between shingles, while at the same time the projections and recesses serve to guide the user in laying the shingles with the desired amount of the individual shingles exposed to the weather.

The, invention will be understood from the description in connection with the accompanying drawings in which g Fig.1 is a plan view of a sheet of roofing material; partly broken away showing how the shingles may be cut;

Fig. 2 is a similar view showing a modification;

Fig. 3 is a similar view showing another modification Fig. 4. is a similar view showing still another modification;

Fig. 5 is a plan view showing an individual shingle as cut from Fig. 1; and

Fig. 6 is a plan view showinghow the shingles may be installed upon the roof or side of a building.

In the drawings reference character 1 indicates a sheet of roofing material sufficiently wide to form two rows of shingles A and B,

This sheet may-be slit longitudinally along the central straight line 2, along the zigzag l ne? and then along the central straight l ne 4.. j The sheet is also cut transversely along the line 5 at right angles to the edges oft-he sheetto form shingles of theproper length. The length of the line 2 is made equal to the length of the shinglethatis to be exposed to the weather when the shingle is installed and should be somewhat less than .one-halfthe length of the shingle, line 4 being of the samelength as line 2. The zigzag line 3 is such that a projection 6 (Fig. 5) of triangular shape and av recess 7 of corresponding shape and size will be formed along one edge of the shingle A. The perpendicular. distance from the point of the projection 6 to the line joining lines 2 and 4 is made equal to the'desired distances between shingles in horizontal rows, the pro.- .jection 6 serving to guidethe user in spacing the shingles'the proper distance apart when the shingle is being installed.

In the modification shown in Fig. ,2 the projection 6' and recess 7' are made with curved lines instead of straightlines as shown in Fig. ,1, .and in the modification shown in Fig. 3the projection 6" and re cess 7" is shown as being rectangular in shape. In the modification shown in Fig. .4, two projections 6' and corresponding recesses 7" are shown. It is obvious that a larger number of projections and recesses could be provided if necessary and that the same could be made with curved-instead of straight lines and. that these projections mightbe made of othershapes, such as square, hexagonal, etc, instead of being madetriangular or circular or rectangular as shown. The shingles can be cut out so that the projections will not have sharp corners to become broken, by cutting the same along curved or circular lines. The straight line alongthe end of the projections 6 as strips that are to be exposed to'ythe weather may be decorated or ornamented in Various ways as, for example, by heating with ahot' implement along selected areas to bring the plastiomaterial out through the interstices of the mineral coating ,by pressing upOI certain areas while the plastic material is hot and in a semi-liquid'state'to'causethe mineral material to become embedded to a greater extent; by applying small strips of material of different colors 'at proper intervals; by providing"streaks of stone surfacing of contrasting color at intervals; or by printing or embossing, etc. The word' shingle as used in this specification and the claims is intended to include either asingl'e shingle or a shingle strip having an edge modified to simulate shingles.

In installing the shingles, a shingle A be placed as indicated in the lower lefthand corner of 6, with the projection 6 turned toward the right. The'ne'xt shingle is laid with its left-hand straight'edge 8 contacting with the end of the projection (Sand with its own projection .6 extending to the right and'so on, for a horizontal row. The shingles in a row may be the shingles A' as shown in Fig. 1, or they may be the shingles B shown in the samefigure turned so that their projections will extend in the same direction as the projections of the other shingles in this row, or they may be amixture of the shingles A andB, the shingles A and B being duplicates of each other when one of them is turned end for end, The shingles may, however, be installed with the other ends extending downwardly so that the proje'ctions (5 would extendtoward the left, but this manner of installing the shingles is usually less preferable than the manner shown in Fig. 6 because the projections 6 would thereby lie farther from the exposed ends of the shingles. qThe next row of shinglesis installed with the lowerend: 9

thereof even with the extreme lowest point 10 of the projection 6. It will be noticed that the extreme upper portion 11 of the recess '7 of this shingle will, at the same time, come exactly even with the upper edge 12 of a shingle in the next underlying row or cours e,. so that the user is guided in laying the shingles with the proper: amount of overlap as well as laying them with proper distances apart in horizontal rows. The shingles will, of course, be installed as usual with joints of successive rows broken. It will be observed that theprojections (5 de fine the upper limits of the spaces between the exposed portions of shingles so as to stop water from passing or being driven any considerable distance upwardly beneath one shingle and between two shingles of an underlying row.

In'cu'tting these shingles from a sheet of rooting material, a sheet of rooting material of twice or anyother multiple of times the width required to make two rows of shingles maybe used, the alternate longitudinal lines,'of course, being straight lines. Or the shingles may be cut transversely across the sheetinstead of longitudinally thereof shown in Fig. 1. In such case the width of the sheet of roofing material is equal to the length of the desired shingles or any convenient multiple thereof.

I claim:

1. A shingle having a projection and a corresponding recess along one edge and substantially "in the center thereof, one edge of said recess forming a continuation of one edge of said projection, and the edges of said shingle being straight and unbroken exceptfor'sai'd recess and projection.

2. A shingle having a projection with an apex and a corresponding recess along one edge thereof on opposite sides of and immediately adjacent the-middle-point of said edge, one edge of said recess forming a continuation of one edge of said projection, and the edges of said shingle being straight and unbroken except for said recess and projection. v

In'testimony whereof I aflixmy signature.
